Die Neuerung "bezieht sich auf ein Vakuumschaltergehäuse, bestehend aus einem Hohlsylinder aus einem anorganischen Isolierstoff, insbesondere aus Glas oder Keramik, in das Metallarmaturen eingeschmolzen sind«The innovation "refers to a vacuum switch housing, consisting from a hollow cylinder made of an inorganic insulating material, in particular made of glass or ceramic, in which metal fittings are melted «

Bekanntlich werden die Vakuumschaltergehäuse aus anorganischen Isolierstoff en,wie z.B. Glas oder Keramik, hergestellt. Von diesen Isolierkörpern wird gefordert, daß sie gegenüber mechanischen und thermischen Spannungen weitgehend unempfindlich sind und daß sie außerdem eine heliumdichte Glasmetallverbindung aufweisen. Unter Heliumdich-As is well known, the vacuum switch housings are made of inorganic insulating material such as glass or ceramics. These insulating bodies are required to be resistant to mechanical and thermal Stresses are largely insensitive and that they also have a helium-tight glass-metal compound. Under helium seal

«£ —11 tigkeit wird eine Leckrate für Luftmoleküle von -10 Torr.Liter/sec verstanden. Um diese Bedingungen zu erfüllen, ist eine gewisse Wandstärke nötig, in die die Metallarmaturen mit der üblichen Glasbläsertechnik jedoch nur schwierig einzuschmelzen sind.«£ —11 A leak rate for air molecules of -10 Torr.Liter / sec Understood. In order to meet these conditions, a certain wall thickness is required necessary, into which the metal fittings are difficult to melt using the usual glass blowing technology.
